defect in an ordinary algorithm
subject			fact

defect in an ordinary algorithm	is a subtopic of 10.4 - Defects in Numerical Algorithms
	is a kind of defect
defect	has example the absence of code to handle an exception
problem	has solution which will normally entail developing software, although you may decide that it is better to purchase software or to develop a non-software solution
	should be written as a simple problem statement in one or two sentences

Kinds of defect in an ordinary algorithm :

• incorrect logical conditions (4 facts) - A common defect in which the logical conditions that govern looping and if-then-else statements are wrongly formulated
• not handling null conditions (4 facts) - A common defect in which a program behaves abnormally when a null condition is encountered
• not handling singleton or non-singleton conditions (4 facts) - A common defect in which a program does not properly handle singleton conditions or non-singleton conditions
• not setting up the correct preconditions for an algorithm (4 facts) - A common defect in which a program proceeds to do its work even when specifies preconditions, that state what must be true before the algorithm should be executed, are not satisfied
• not terminating a loop or recursion (4 facts) - A common defect in which a loop or a recursion does not always terminate, i.e. it is 'infinite'
• off-by-one error (5 facts) - A defect in which a program inappropriately adds or subtracts one, or inappropriately loops one too many times or one too few times
• operator precedence error (6 facts) - A defect in which a programmer omits needed parentheses, or puts parentheses in the wrong place
• performing a calculation in the wrong part of a control construct (6 facts) - A common defect in which the program performs an action when it should not, or does not perform an action when it should
• use of an inappropriate standard algorithm (5 kinds, 4 facts) - A common defect in which an unnecessarily inefficient or otherwise inappropriate algorithm is used
